嘿伙计们，我正在处理的任务有问题。
代码如下：
#include <iostream>
#include <fstream>
#include <iomanip>
#include <cmath>
#include <cstdio>
#include <cstring>
using namespace std;
class payroll
{
private:
char empnum[10];
char empfirstname[150];
char emplastname[150];
char empsin[9];
char empdob[10];
char empphone [15];
char empstreet[100];
char empcity[60];
char empprovince[150];
char empcountry[200];
char empstatus[50]; //Employee status. EX: Terminated, On leave, Active etc.
int empsalaryei;
int empsalaryfedtax;
int empsalarycpp;
int empsalarynet;
int empsalarygross;
public:
void addrec(void);
void modrec(void);
void viewrec(void);
void exit(void);
};
payroll rec;
payroll emp;
ifstream inFile1;
ifstream inFile2;
bool check = false;
int main()
{
system("CLS");
char ch;
do
{
cout<<"1. Add an employee\n";
cout<<"2. Modify employee record\n";
cout<<"3. View employee record\n";
cout<<"0. Exit\n";
cout<<"Please choose an item: ";
if (check == true)
{
system("CLS");
ch=0;
}
else
cin>>ch;
switch(ch)
{
case '1':
emp.addrec();
break;
case '2':
emp.modrec();
break;
case '3':
emp.viewrec();
break;
case '0':
emp.exit();
return 0;
}
}while(ch !=0);
return 0;
}
void open_employee_info() //function to open employee data file
{
string filename1 = "employee-details.dat"; //define which file to open
inFile1.open(filename1.c_str()); //open our payroll file
if(inFile1.fail()) //if our file open fails....
{
cout << "\nSorry the file was not opened successfully"<< "\n Please check that the file does exist or create it" << endl;
exit(1);
}
cout << "\n The file was opened successfully" << endl;
}
void open_payroll_info() //function to open payroll salary information file
{
string filename2 = "payroll-info.dat"; //define file name
inFile2.open(filename2.c_str());
if(inFile2.fail())
{
cout << "\nSorry the file was not opened successfully"<< "\n Please check that the file does exist or create it" << endl;
exit(1);
}
cout << "\n The file was opened successfully" << endl;
}
void payroll::addrec(void) //Record adding
{
char userinputadd = ' ';
cout << "\nPlease Enter the Employee number: ";
gets(rec.empnum);
cout << "\nPlease Enter the Employee's First Name: ";
gets(rec.empfirstname);
cout << "\nPlease Enter the Employee's Last Name: ";
gets(rec.emplastname);
cout << "\nPlease Enter the Employee's Date of Birth (mmddyyyy): ";
gets(rec.empdob);
cout << "\nPlease Enter the Employee's Social Insurance Number: ";
gets(rec.empsin);
cout << "\nPlease Enter the Employee's Phone Number: ";
gets(rec.empphone);
cout << "\nPlease Enter the Employee's Address: ";
gets(rec.empstreet);
cout << "\nPlease Enter the Employee's City: ";
gets(rec.empcity);
cout << "\nPlease Enter the Employee's Province: ";
gets(rec.empprovince);
cout << "\nPlease Enter the Employee's Country: ";
gets(rec.empcountry);
cout<<"\nPlease Enter the Employee's Status: ";
gets(rec.empstatus);
cout << "\nPlease Enter the Employee's Weekly Gross Salary: ";
cin >> rec.empsalarygross;
cout<<"Would you like to return to the main menu?(y), else the program will exit: ";
cin>>userinputadd;
if (userinputadd =='y' || userinputadd =='Y')
main();
else
exit();
}
void payroll::modrec(void) //Record Modification
{
system("CLS");
int empmodnum=0;
check = false;
char userinputmod = ' ';
cout<<"\nEnter the employee number for the record you would like to modify: ";
cin>>empmodnum;
cout<<"Would you like to return to the main menu?(y), else the program will exit: ";
cin>>userinputmod;
if (userinputmod =='y' || userinputmod =='Y')
main();
else
exit();
}
void payroll::viewrec(void) //Record viewing
{
system("CLS");
check = false;
char userinputview = ' ';
cout<<"Would you like to return to the main menu?(y), else the program will exit: ";
cin>>userinputview;
if (userinputview =='y' || userinputview =='Y')
main();
else
exit();
}
void payroll::exit(void)
{
inFile1.close();
inFile2.close();
check = true;
}
因此，如果您在前面的菜单中按 1 添加记录，您会看到它跳过了第一个 cin 语句，即员工编号。
有谁知道为什么会发生这种情况？
